Alejandro, Can you explain why you added -delete-orphan? <set name="objectProperties" | table="JBPM4_DEPLOYPROPS" | cascade="all-delete-orphan"> | <key column="DEPLOYMENT_" /> | <one-to-many class="org.jbpm.pvm.internal.repository.DeploymentProperty" /> | </set> I don't see a problem with it. But I also don't see why it would be necessary as deployment properties would never be removed anyway. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4261186#...
